SHEET FOR OPTICAL-SEMICONDUCTOR-ELEMENT ENCAPSULATION AND PROCESS FOR PRODUCING OPTICAL SEMICONDUCTOR DEVICE WITH THE SAME

摘要

The present invention provides a sheet (1) for optical-semiconductor-element encapsulation, which comprises: an outermost resin layer A (2) that is to be brought into contact with one or more optical semiconductor elements (6); a light-diffusing layer (3) formed on the layer A (2) and containing light-diffusing particles; and a resin layer B (4) formed on the light-diffusing layer (3) and having a lower refractive index than that of the layer A (2). Also disclosed is a process for producing an optical semiconductor device using the sheet (1).
